Method for determining transmission bandwidth, device and storage medium
View Patent ↗The embodiments of the present disclosure provide a method for determining a transmission bandwidth, a device and a storage medium. In the method, after configuring an unlicensed carrier for a terminal device, a network device performs channel detection on sub-bands on the unlicensed carrier, then determines, according to the detection result, which sub-bands are used for communication, indicates said sub-bands by means of first indication information, and then sends the first indication information to the terminal device; the terminal device determines, according to the first indication information, the sub-band on the unlicensed carrier for transmitting a downlink channel and/or downlink signal by the network device.
1. A method for determining a transmission bandwidth, comprising:
sending, by a network device to a terminal device, first indication information used for the terminal device to determine one or more sub-bands on an unlicensed carrier that are used for communication, wherein the unlicensed carrier comprises at least two sub-bands, the first indication information is used to determine the sub-band with a smallest index in a first sub-band and a number of sub-bands included in the first sub-band, and the first sub-band comprises sub-bands used for communication among the sub-bands comprised in a first bandwidth part (BWP) of the terminal device.
2. The method according to claim 1 , wherein the method further comprises:
sending, by the network device, a PDCCH to the terminal device, the PDCCH comprising the first indication information.
3. A non-transitory computer-readable storage medium, configured to store a computer program, wherein the computer program causes a computer to perform operations comprising:
sending first indication information to a terminal device, the first indication information being used for the terminal device to determine one or more sub-bands on an unlicensed carrier that are used for communication, wherein the unlicensed carrier comprises at least two sub-bands, the first indication information is used to determine the sub-band with a smallest index in a first sub-band and a number of sub-bands included in the first sub-band, and the first sub-band comprises sub-bands used for communication among the sub-bands comprised in a first bandwidth part (BWP) of the terminal device.
4. The storage medium according to claim 3 , wherein the operations further comprise sending a PDCCH to the terminal device, the PDCCH comprising the first indication information.
